'BERNARD P. BOGY, OF ST. LOUIS, MISSOURI.

HINGE.

SPECIFICATION forming part of Letters Patent No, 308,739, dated December2, 1884.

(No model.)

the city of St. Louis and State of Missouri,

have invented a certain new and useful Iniprovenient in Hinges, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification',and in which- Figure lis an end view. Fig. 2 is a side view showing thehinge open, and Fig. 3 is a side view with the hinge closed.

My invention relates to those hinges more particularly intended for useonpark and other gates, but which may be used for any other purposedesired, so constructed that the gate or other object to which they aresecured will swing shut automatically after being opened; and myinvention consists in fea' tures of novelty hereinafter fully described,and pointed out in the claim.

Referring tothe drawings, A B represent the leaves of the hinge, whichmay be of any ordinary shape; A B', the ears,and Cthe connectingpintle.The upper and lower parts, a a', of the ears A of the hinge are inclinedat any desired pitch, and the upper and lower parts, b b', of the ears Bcorrespondingly in-` clined, (or vice versa,) as represented. Theseinclined faces have fric-tional contact, and it will be understood byreferring to Figs. 2 and3 that as the gate is opened it will be raisedslightly, and when released will close by gravity, theinclined faces ofthe parts of the hinge secured to the gate sliding down the inclinedfaces of the parts secured to the posts orsupport. A hinge thusconstructed is reversible, and is as cheap, strong, and durable as anordinary leaf-hinge, and is effective in accomplishing the purpose forwhich it is designed. This forni of hinge will often be found veryuseful, as either end can be putA up, thus placing the projection partsof the ears in either direction,whilethe operation of the hinge remainsthe same. In turning the leaf B from the right to the left on the leaf Ait will be seen that th-e inclines b' slide down on the inclines a, andin turning the leaf A from the left to the right on the leaf B that theinclines a slide down the inclines b.

I claim as my invention- A reversible hinge consisting of a leaf, A,having ears A', formed with upper inclines, a., and lower inclines, a',a leaf, B, having ears B', formed with upperinclines, b, and lowerinclines, b', and a pintle, G, to secure the leaves together by theears, the lower inclines, b', adapted to slide down the upper inclines.a., in turning the leaf B to the left on the leaf A, and the lowerinclines, c', adapted to slide down the upper inclines, b, in turningthe leaf A to the right on the leaf B, as set forth.
